cats care

A while ago my parents moved to the farm in Eastern Europe. They had one cat with them. Sadly, older generation do not feed cats, also they do not believe/some can not afford sterilisation and still use brutal ways of "birth control". My mum (who is a pensioner now and receives very tiny pension), initially sheltered a cat with new born kittens who's owner was threatening to destroy them. So far my parents have managed to sterilise one cat. Therefore no surprise the quantity of them keeps increasing. At this moment and time we have 11 cats living on the farm and 4 additional ones coming for a feed. I would like to ask kind people to donate whatever they can so cats could be sterilised. If amount raised is greater than requested, the funds would go for their food. Thank you all in advance!
